Foot arch support



March 15, `1932. F. J. scHoLL FOOT ARCH SUPPORT Filed Dec. 2, 1930 Patented Mar. 15, 1932 UNITED STATES PATENT OFFICE g FRANK JOHN scHoLL, oF LONDON, ENGLAND FOOT ARCH SUPPORT Application led December 2, 1930, Serial No. 499,571, and in Great Britain September 1, 1930.

Metal or other stiff material foot arch supports are known in which the undersides are so hollowed that at some part or parts rela- Y tively narrow edges are presented towards the inner soles of foot-wear with which the supports are used and which'edges, to prevent or reduce chafing and wear of the inner soles are provided with protecting means that may take the form of pads of suitable material secured to the supports in any suitable way, either permanently or in a removable manner.

One way in which a protecting pad has been secured to the metal plate of a foot arch support in a removable manner has been by directly attaching it to the underside of the forward end of the plate by means of bifurcated studs or screw studs carried by the plate, the rear portion of the pad being split and one part formed with holes through which the studs extend sufciently to be bent over or to receive domed shallow nuts the other split part being pasted down over the bent over or nutted ends of the studs. Such f a method of attachment permit the pads to be readily removed after pulling back their pasted down parts, and has the advantage that the studs cannot project into contact with and cause damage to the inner sole as happens when studs extend right through the pad, but it has the disadvantages that the pasting down of the split portion must be carefully done to avoid mess and that some interval of time before use has to be allowed in order that the paste may properly set.

Now according to this invention studs carried by the plate of the support project from its underside as in the previous arrangements hereinbefore referred to and the holes in the pad are made of two diameters, the studs projecting through the smaller portions of the holes into the larger portions but not beyond the surface of the pad and small nuts r or spring washers are applied to the projecting ends of the studs and occupy the larger portions. Preferably the studs are screwed to receive nuts notched for engagement by a key whereby they can be easily turned although closely fitting the holes. lVhere the pad is of leather, hard wearing fabric or thelike material, a thin metal or otherplate is introduced into the body of the material and A into the holes so as to bed upon the shoulderstherein and be firmly held in place.

Referring to the accompanying drawings:

Fig. 1 is an underside view. Figs. 2 and 3 sections on the lines 2 2 and 3-3 respec- ,tively of Fig. l and Fig. i a perspective view of the pad and associated metal plate.

The foot arch support comprises a plate a which may be of metal and the forward edge of which is prevented from contacting with the sole of foot wear by a pad b of leather or other suitable material formed with holes c of larger diameter at the underpart than at the upper part. Z is a thin metal reinforcing or protecting plate fitted between split portions of the pad which are then secured together by adhesive. Short screw studs e project from the underside of the support a into the holes c and notched nuts f are screwed onto the studs so as to secure the pad to the underside of the support. The notched nuts f closely fit the larger portions of the holes but can be easily removed by means of a key with prongs engaging the notches. The plate a of the support may be of suitable material other than metal, though metal is generally the preferable material, and it may have attached to it a leather or like covering as well understood.

What I claim is 1. A foot arch support comprising a supporting plate, an edge protecting pad having holes, a metal reinforcing plate carried by said pad and having corresponding holes, studs carried by the supporting plate and projecting through the holes in the reinforcing plate and into the holes in the pad, and detachable securing Vmeans applied to the Cil studs and occupying the holes in the pad and bearing against the reinforcing plate.

2. A foot arch support comprising a supporting plate, an edge protecting pad having holes, a metal reinforcing plate having corresponding holes and embedded in the pad, screw studs projecting into the holes in the pad and through those in the reinforcing plate, and nuts applied to the screw studs and occupying the holes in the pad.
